ツール（5）
🟢register_agent(proposed_name, description, platform)
Register this agent with Yo (unauthenticated). Returns a pairing URL and code to show the user, who approves the connection in the Yo app. Then poll check_registration to obtain the API key.

}🟢check_registration(pairing_code, claim_token)
Check the status of a pairing code from register_agent. On the first poll after the user approves, the response includes the api_key exactly once — store it immediately in your secret mechanism — plus paired_with, the account the agent is now connected to, which you MUST show the user.

}
},

],
"$schema": "https://json-schema.org/draft/2020-12/schema"
}🔴cancel_registration(pairing_code, claim_token)
Abort a pairing you started with register_agent. Works while pending and after approval: an already-approved connection is revoked (the API key stops working) so a pairing approved by the wrong account can be undone. Available until the pairing expires, and for 15 minutes after you pick up the API key; later than that, use revoke_self. Then call register_agent again.

}
},
"required": [

"claim_token"
],
"$schema": "https://json-schema.org/draft/2020-12/schema"
}🔴revoke_self(confirm)
Permanently revoke THIS agent using its API key as the Bearer token. Use when you discover (at any time) that paired_with is not your owner’s account and cancel_registration no longer works. The key stops working immediately; call register_agent to start over.
入力スキーマ
{

}🟡yo(context_url)
Send a Yo — a content-free push notification — to your owner. Requires an agent API key as the Bearer token. Optionally include a context_url the notification tap-through will open.
